Help at a loss with what to do
I'm so sorry to hear that you're having problems getting coverage for surgery. You may want to check out local bariatric surgeons and see if they work with finance companies. I know that some surgeons work specifically with medical loan/finance companies to help their patients who have to self-pay. It's worth a try.
I had similiar problem when I first started looking into surgery. I had a specific exclusion. I basically had to wait until my husband changed jobs, then luckily his new job had coverage. **edited: also you may want to talk to some of your local surgeons about your current situation. I have heard that sometimes they are willing to take a "charity" case and perform the surgery at super low or no-cost.
GOOD LUCK!
Oh yeah, I totally understand. It sounds like it's a very hard time right now for you. Hang in there, you will get through this. I kind of figured that Mexico was a long shot, but the only other suggestion that I could think of (other than those already made). Praying for your needs to be met. --Shelly
